8508 (grokparms): Return 0 if arg_types is error_mark_node.
8509 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with

8513 (finish_struct, finish_enum): Remove redundant diagnostics.
8514 (build_enumerator): Don't cascade diagnostics for error_mark_node.
8515 Mark location where -pedantic changes the meaning of the program.

8546 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
8547 correct loop over multiple translation units; call fatal_error if
8548 requested to compile more than one file at once. (This disables
8549 IMA temporarily - an up-front error being preferable to a crash.)
8550 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
8551 (all actions): Adjust calls to pushlevel/poplevel.
8552 (parsing_iso_function_signature): Delete.

8562 to suppress -Wold-style-definition after this error.

13277 2004-02-11 Per Bothner <per@bothner.com>
13279 Represent column numbers using line-map's source_location.
13280 The "next available source_location" is now managed internally by
13281 line-maps.c rather than by clients.
13282 * line-map.h (struct line_map): New field column_bits.
13283 <from_line>: Rename field to start_location.
13284 (struct line_maps): New fields highest_location and max_column_hint.
13285 (linemap_check_files_exited): New declaration.
13286 (linemap_line_start): New declaration.
13287 (linemap_add): Remove from_line parameter; use highest_location field.
13288 (SOURCE_LINE, LAST_SOURCE_LINE): Modify to use column_bits.
13289 (SOURCE_COLUMN, LAST_SOURCE_LINE_LOCATION): New macros.
13290 (CURRENT_LINE_MAP): Remove macro.
13291 (linemap_position_for_column): New inline function.

13296 (linemap_line_start): New function.
13297 (linemap_lookeup): Update for new field names.
13298 * cpphash.h (struct cpp_reader) <map>: Field removed. Because
13299 linemap_position_for_column may unpredictably change the current map,
13300 it is cleaner and simpler for us to not cache it in cpp_reader.
13301 (struct cpp_buffer): New sysp field.
13302 Changed warned_cplusplus_comments and from_stage3 to bitfields.
13303 * cppinit.c (cpp_read_min_file): pfile->map no longer exists.
13304 * cpplib.c (do_line, do_linemarker, _cpp_do_file_change): Get
13305 current map using linemap_lookup.
13306 (do_linemarker): Also set buffer's sysp field.
13307 (destringize_and_run): No longer need to decrement current line.
13308 * cppfiles.c (_cpp_stack_file): Set sysp from and in buffer.
13309 (search_path_head, open_file_failed): Use buffer's sysp.
13310 (cpp_make_system_header): Get current map using linemap_lookup.

13313 * cpphash.h (CPP_INCREMENT_LINE): New macro.
13314 (struct cpp_buffer): Moved fields saved_cur, saved_rlimit to ...
13315 (struct cpp_reader): ... and adding saved_line_base field.
13316 * cpptrad.c (_cpp_overlay_buffer, _cpp_remove_overlay):
13317 Update accordingly. Don't adjust line.
13318 (_cpp_scan_out_logical_line): Use CPP_INCREMENT_LINE.
13319 * cpphash.c (CPP_IN_SYSTEM_HEADER): Replaced macro by ...
13320 (cpp_in_system_header): ... new inline function, using buffer's sysp.
13321 * cpperror.c (_cpp_begin_message): Update to use cpp_in_system_header.
13322 * cpplex.c (_cpp_lex_direct): Likewise.
13323 * cppmacro.c (_cpp_builtin_macro_text): Likewise.
13324 * cppmacro.c (_cpp_create_definition): Use buffer's sysp field.

13326 Remove col field as it is now subsumed by src_loc.
13327 * cpperror.c: Update various field, parameter, and macro names.
13328 (print_location): If col==0, try SOURCE_COLUMN of line.
13329 (cpp_error): Use cur_token's src_loc field, rather than line+col.
13330 * cpplib.c (do_diagnostic): Token's src_loc fields replaces line+col.
13331 * cpplex.c (_cpp_process_line_notes, _cpp_lex_direct,
13332 _cpp_skip_block_comment): Use CPP_INCREMENT_LINE.
13333 (_cpp_temp_token): Replace cpp_token's line+col fields by src_loc.
13334 (_cpp_get_fresh_line): Don't need to adjust line for missing newline.
13335 (_cpp_lex_direct): Use linemap_position_for_column.
13336 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
13337 parameter. Instead get it from the line_table global. Adjust callers.
13338 (print): Remove map field. Replace line field to src_line.
13339 (init_pp_output, account_for_newlines, maybe_print_line): Adjust.
13340 (cb_line_change): Use SOURCE_COLUMN. Minor optimizations.
13341 (pp_file_change): Use MAIN_FILE_P since we cannot checked print.map.
13342 Use LAST_SOURCE_LINE_LOCATION to "catch up" after #include.
13343 * cpptrad.c (copy_comment): Rename variable.
13344 * c-lex.c (map): Remove static variable, for same reason we removed
13345 cpp_reader's map field.
13346 (cb_line_change, cb_def_pragma, cb_define, cb_undef): Hence we need
13347 to call linemap_lookup.
13348 (cb_line_change): Token's line field replaced by src_loc.
13349 (fe_file_change): Use MAINFILE_P and LAST_SOURCE_LINE macros.
13350 Don't save new_map.
